1 Claim.

This invention relates to a holder for sandpaper.

An object of this invention is to provide a holder for sandpaper whichincludes a sheet metal body having a pair of parallel inverted U-shapedjaws within which a pair of upwardly convergent flanges carried by abottom plate are adapted to be engaged, with the flanges having means ateach end thereof to hold the bottom plate against endwise movement.

Another object of this invention is to provide a holder of this kindwhich is of simple construction and can be formed out of stamped sheetmetal.

A further object of'this invention is to provide a holder of this kindwherein the bottom plate may be shaped in a manner to conform closely tothe shape of the work which is being sanded.

With the above and other objects in view, my invention consists in thearrangements, combination and details of construction disclosed in thedrawings and specification, and then more particularly pointed out inthe appended claim.

In the drawing:

Figure 1 is a plan view of a sandpaper holder constructed according toan embodiment of this invention,

Figure 2 is a sectional view taken on the line 22 of Figure 1,

Figure 3 is a sectional view taken on the line 33 of Figure 2,

Figure 4 is a fragmentary sectionalview taken on the line 4-4 of Figure3,

Figure 5 is a fragmentary sectional view taken on the line 55 of Figure3,

Figure 6 is a detail end elevation of fled form of bottom plate,

Figure 7 is a detail end elevation of another modified form of bottomplate,

Figure 8 is a detail end elevation of another modification of thisinvention.

Referring to the drawing, the numeral l designates generally anelongated handle which is formed of sheet metal and includes a pair ofdownwardly convergent sides Ii which merge with a pair of downwardlydivergent plates or walls l2. The plates or walls l2 have formed on thelower edges thereof inverted substantially U- shaped clamping membersl3, the purpose for which will be hereinafter described. A bottom platel4 of transversely arcuate configuration is provided in the oppositelongitudinal edges thereof with a pair of upwardly convergent flanges lwhich are adapted to engage within the clamping member l3 and eachflange I5 is a modiformed adjacent the opposite end thereof with detentsI6 which provide a means for holding the flanges l5 and the bottom plateI 6 against endwise movement with respect to the clamping members I3.The bottom plate I 4 is formed with upturned opposite ends i1 and thelower side of the bottom plate 14 has secured thereto a cushion memberIB. The cushion member i8 may be formed of either rubber, felt or thelike and a sandpaper sheet [9 is adapted to engage under the cushionmember [8 and the opposite longitudinal edges of the sandpaper [9 arebent about the flanges l5 as shown in Figure 3 and indicated at 20. Thereverted or returned edges of the sandpaper [9 are adapted to engage inthe clamping members l3 so that the clamping members I3 will firmly holdthe sandpaper on the flanges l5 and under the cushion member 18.

Referring now to Figure 6 there is disclosed a modified form of bottomplate where in the plate member 2|, which is provided with theupwardlyconvergent side flanges 22, is formed with a transversely arcuateportion 23 having the concave side thereof lowermost and a cushionmember 24 is adapted to be secured to the bottom' plate 2| by anysuitable fastening means such as adhesive or the like.

Referring now to Figure '7, there is disclosed, a modification of thebottom plate generally designated as 25. The bottom plate 25 is formedwith upwardly convergent side "flanges 26 and an inverted V-shapedintermediate portion 21. The inverted intermediate portion 21 is formedwith right angular sides so that the right angled corner of a workposition can be readily sanded. The bottom plate 25 is also providedwith a cushion member 28 which may be formed of rubber, fibrous materialor the like.

Referring now to Figure 8 there is disclosed another modification ofbottom plate generally designated as 29 which is formed with V-shapeoiwalls 30 having extending from the upper divergent edges thereof,upwardly convergent flanges 3|. A bracing plate 32 is fixed between thesides of the bottom member 29 and a cushion member 33 is secured in anysuitable manner to the outer side of the bottom member 29. It will beunderstood that if desired, the bottom plate 29 may be formed with aconvex wall which may be braced after the manner shown in Figure 8 sothat concave surfaces may be readily sanded.

In the use and operation of this device the sandpaper 9 is cut somewhatlarger than the width of the bottom member [4 and the longitudinal edgesof the paper H! are then bent upwardly and downwardly over theconvergent flanges IS. The bottom member is then pressed into theclamping members 13 and it will be understood that the divergent sidemembers or plate I2 carried by the handle 10 are of resilientcharacteristic and may be biased outwardly so that when the bottommember is engaged with the clamping members the clamping members l3 willfirmly hold the flanges of the bottom member in the clamping "membersl3. The buttons or detents l6 engage in the opposite ends of'theclamping members [3 and hold the bottom member against endwise movementrelative to the handle l0 and the divergent members l2.

This holder may be stamped or otherwise formed out of sheet metal havinga resilient characteristic and where the "device -is" tobeuse'd insanding a flat surface the bottom member, shown in Figure 3, will beused. By providinga slight curvature to the bottom member M, the sandpaper l-9wil l tend to straighten :out "the curvature f of the "bottommember I' l and therefore-prevent undue engagement of the oppositelongitudinal edges of the bottom member with the work.

I do notmean'to confine myself to the exact details ofconstructionherein disclosed but claim .all variations falling withinthe purview of-the appended claim.

What I claim is:

A sandpaper holder comprising an elongated handle formed of sheet metal,a pair of angularly inclined side portions diverging from said handle, asubstantially U-shaped reverted downwardly opening clamping jaw carriedinwardly of the lower edge of each portion, a bottom plate, upturnedends on said bottom plate, a pair of upwardly convergent, resilientlyexpansible identical flanges carried by the -'qp osite :longitudinaledges of said bottom plate and engageable with said jaws interiorly ofsaid angularly inclined portions and a detent adjacent each end of eachflange for holding said flanges against endwise movementrelative to saidjaws.
